SlipstreamVX is a fundamentally new way of simulating and rendering smoke, wind, dust and fire effects in Softimage 2010, 2011 and 2012.


Fast Shot Setup and Turnaround
Nothing in the market compares with SlipstreamVX's speed. When you create a simulation scenario and press play for the first time, the SlipstreamVX simulation often plays back at better than real-time speeds, even with detailed simulations.
Deep Softimage ICE Integration
Exocortex worked with production Softimage TDs in the development of the Softimage SlipstreamVX interface. As a result, SlipstreamVX is designed from the start as an ICE-based simulator that both leverages the power and the flexibility inherent in ICE. SlipstreamVX isn't just a black box simulator that has been made into an ICE node.
Simulation Boxes are Obsolete
SlipstreamVX brings to VFX artists a fundamentally new method of fluid simulation, a method that no longer requires the otherwise ubiquitous and limiting "simulation box." SlipstreamVX simulations can be anywhere in your scene and go anywhere. You can now focus on achieving the simulation behavior rather than how you should place and update your "simulation box."
GPU-Accelerated Rendering
We understand that a great simulator is nothing if you can't easily render the results. We decided to go further than just providing a renderer, we made a lightning fast GPU-accelerated renderer so that you can render your simulation results as fast as SlipstreamVX can simulate them. Our new renderer, Fury, can render luminous simulation as well as do near instantaneous density integration. Hassle-free self-shadowing is on the way.

RLM-Based Floating Licenses

Exocortex's plugins now support RLM-based licensing. RLM stands for "Reprise License Manager." Conceptually RLM is similar to the FlexLM/LMtools system that is employed by Autodesk products.

RLM Server Setup

To utilize RLM-based floating licenses, you must have an RLM license server setup.

Quick Start

The following is a quick-start guide to using RLM. This is a very simplistic setup, but it should get you going quickly:

  1. Download Exocortex's RLM tools package (from here ) and unzip it somewhere.
  2. Create a directory in the root drive called "rlmtools", so that it looks like this c:\rlmtools
  3. From the Exocortex RLM Tools package, copy the two exe's for your platform and the *.set file (exocortex.set, rlmutil.exe and rlm.exe) into c:\rlmtools
  4. Start a command prompt and navigate to c:\rlmtools
  5. Run "rlmutil rlmhostid", and you get a host ID. If you have multiple hostids, just use the first one.
  6. Run "rlm" and you get a server name (licenseserver) and license port (5053 - for you, and 5054 - for the webserver).
  7. Fill-in the Exocortex webform for the license with your hostid, license server name, and license port. The webform will generate for you a RLM license file with a *.lic extension.
  8. Place a RLM license file (.lic) in the c:\rlmtools folder, and re-start "rlm" (press Ctrl-C to exit RLM, type "rlm" at the command prompt to run it again.
  9. Firewalls will block RLM license server requests, thus to get going quickly, it is easiest to disable them. Please consult the RLM User Guide for proper firewall configuration.

If you want a permanent RLM license server setup, you will have to install RLM as a service. This can be done via calling "rlm" with the "-install_service" command line option once you know everything is working properly.

Advanced Users

Reprise Software has a detailed online manual that describes how to setup the RLM server and its associated options. It is available online here:

In order to serve licenses to Exocortex products, you require from Exocortex both its vendor specific setting file, which is called exocortex.set and your license files. Exocortex's RLM daemons for both Windows and Linux can be found in the Exocortex RLM Tools package, which can be downloaded from here:

The configuration options related to Exocortex's ISV-specific daemon are fully described in the RLM End User manual above.

Working with other RLM-licensed products

Different RLM licensed products, even from different vendors, can usually be served from the same RLM server. Generally the procedure to server multiple products from the same RLM server installation is straightforward. The main requirement is to place all the license files and all the vendor/ISV specific deamons/*.set files into the same directory. Each license file must specify the same host along with the same host port. It is this shared server port (usually 5053, although it can be customized) which one should specify that each client should connect to.

RLM Client Setup

To setup your clients so that they can check out licenses, you need to configure either the RLM_LICENSEenvironment variable (which is shared by all RLM licensed products) or the exocortex_LICENSE environment variable (which is specific to Exocortex products) so that they are in the form "[port]@[licenseserver]". Once you have done setup the license server as well as the client environment variable, it should be possible to use the RLM floating licenses with your Exocortex products.

There are a number of options for setting these environment variables. You can set it globally on the machine or you can set it specific to Softimage (Go to Softimage setenv and write exocortex_LICENSE=port@licenseserver.)

Disabling Node-Locked Activation to enable RLM

In some cases our node locked activation can prevent you from using your RLM licenses. This can happen when you activate a trial license and then switch over to using RLM during your trial period. This issue is fixed in our more recent plugins, but for earlier plugins you can fix this issue by deleting the *.lic that is located in the equivalent directory:


Resolving issues with RLM Floating Licenses

Exocortex's products that have RLM capabilities will display RLM-specific diagnostic information in the Softimage log when it is looking for an RLM license and one can't be found or accessed. If there are issues with RLM now working, checking the log information can be very helpful in resolving the issue.

If you are unable to resolve the issue, please contact and provide as much detail as you can about your configuration and the error that is occurring.
